To all whom it may concern.'

Be it known that L EVERETT C. lVlUnDion,

New Jersey, have invented certain new anduseful Improvements in Carpet-fweepers, of which the following is a description, ref-v erence being 'had to the accompanying drawing and to the letters and figures ot' reference marked thereon. c

y My invention relates togcarpet sweepers, aiiddsmore particularly an improvement on the carpet sweeper patented to me March 29th, 190i, No. 146,042.-

The object of the present invent-ion is tov provide animproved means for brush `adjust-ment whereby .the brush may bel ad justed vertically, whereby it .may engage the carpet more or less deeply, according `to .the texture thereof, suchadjustinent providing the variations in the amount of nap o n the various kinds of ycarpets or rugs.

. Broadly speaking, adjustable bearings for the` brushes of carpetsweepers are not new,

the case is' provided with anlendband, the

but my invention consists more particularly yin -an adjustment for the type of sweeper setforth the aforesaid patent, in which brush 'with an end socket, and a flat spring piecelyingalong the end band cari-ies a pin entering said'sock'et, the spring piece being 'free at one end.

thel present invention for the slight vertical swinging of the spring piece' to'vary the verticalposition of' the brush, with means for holding the spring piece securely in the position to which' it may be moved.

The invei'ition is illustrated in the accoin panying drawings, in which, Figure 1 is a horizontal section of a portion of a carpet sweeper embodying my invention; Fig. 2 is an end view; and Fig. 3 a detail view of the leverand lock.

vIn these drawings, reference may be had to my former patent for a general description of the sweeper, l, 1, being the sweeper whleels: 2 the brush, and 3 the case. 'I he end band is shown at 4 and 5 is the spring piece which is riveted at 6 to the end band. The spi'ingpiece carries the pin 7, which asses through a vertical'slotv 1n the end and into a socket 9, in the end of the brush.

.- More particularly, consists --in provision specification of'Letters-fratet.

Application filed .T illy 26,1911. Serial Na/10,673.

ln the present invention, the spring piece 5 has the projecting finger holds 10, and the end of the body portion between the finger pieces is formed with,a 'plurality of open end. slots l1, adapted to receive a pin 1Q on the lower end of a iiiigeiilcver 13, pivo-ted at 14 to the end band, and having a linger or thumbpiece 14. The pin 12 moves in a curved slot-.15 in the end band, and is preferably headed, as shown iii Fig. 3, the head engaging the slightly upturned ends 16 of the nger holds l0, so thatthe spring piece 5 is i'nily held in `tlat position against the end band.

The operation will be readily understood..v

Assuming the parts in the position shown in Fig. 2, and another adjustment of the brush Vis desired, the finger lever 13 is swung to draw the pin 1Q out of the slot with which it is in engagement, the piece 5 is swung up or down as the case may be to move the brush' up or down, and the lever 13 then manipulated tolock the piece 5 in its new position.

if desired to remove the brush, of course, the piece 5 must to release the pin 7 from the socket 9.

' Having thus described iiiy invention, what 'I claim as new and desire to secure by Let ters Patent, is y y l. In a carpet sweeper the combination of a case, a brush with-an end socket, a nieiii'- bei' mounted on the case and carrying a pin to be received into said socket, said member being supported so as to 'swing vertically.

be 'swung out horizontally and having a series of slots formed adjacent the free end thereof, a pin adapted to en.- gage one of said slots for holding said ineinber in ad] usted position, and means for movy ing` thecpin from one slot to another.

2. In a carpet sweeper, the combination of a case with an end band, a brush with an end socket, and a member lying'along the end band carrying a pin to be received into such socket, said member being supported A so as to swing vertically, and havingla series of slots Jformed adyacent its free end, and

ii swinging lever having apin adapted to engage said slots.

3. Iny a carpet sweeper, the combination of a case vwith anend band, a brush `with an`` `end socket, and av member lying alongthe end band carrying a pin to be received into of. s10ts formed adjacent its free end with outwardly turned side wa11s, and'zr` swying. 'ing' lever-h'vinga pm engagmg saidsluts,
